heres my thinking, not saying all these should be on the list, but atleast get a mention: -
Sopwith Camel (most kills in WWI) or Se5a which was just as good.
As for the fokker triplane it was not really ground breaking (was copied from sopwith triplane) nor was it that great unless in the hands of a brilliant pilot.
DeHavilland Comet? the first jet airliner
Harrier
suprised no one has mentioned Boeing 737 or 747.
cant really take the list seriously when it doesnt include the wright flyer or bleriot.
Concorde gotta be there really

As for B-17 some would argue that the B-24 was better, Lancaster more versatile, B-29 more groundbreaking in terms of tech.
F-117? first stealth plane into service?
depends on judging criteria really.
